A phrase coined by You Tube star Shane Dawson after making a "Twilight" parody video where his Edward
Cullen character is
fed by the Bella character (Brittani Louise
Taylor) from a cup of her period blood.
Shane Dawson (
Edward): Bella, I want your blood but I don't want to kill you to get it."
Brittani Louise
Taylor (Bella): "Wait, I'm on my period. I can't believe I never thought of this before."
*Uses glass to collect period blood for Edward*
This glass of blood is the "periodcup".
"I
love Edward Cullen so much, I'm going to start using a periodcup".
